Description
Technical field
The present invention relates to a kind of shock absorber, especially a kind of microspheric form tooth shape shock absorber, belong to vibration absorber technology neck
Domain.
Background technology
Retrieval understands that the U Chinese patent literatures of CN 205523648 disclose a kind of engineering truck shock absorber, including rubber
Colloid, T-shaped plate and ring spring vibration absorber；Rubber bodies are hollow ring body, including rubber body, are opened in rubber body
Through hole on mandrel line and the breach for being arranged on rubber body bottom edge surrounding；T-shaped plate is hollow T-shaped body, including horizontal stroke
Plate, the riser perpendicular to transverse slat center and it is opened on riser central axis and implements the bolt hole of transverse slat；Ring spring subtracts
Vibrating device includes annular upper bracket, spring body and annular lower carriage, the both ends of spring body respectively with annular upper bracket and annular
Support is connected；The riser of T-shaped plate runs through the through hole into rubber bodies, the axial length size of riser be less than the depth size of through hole,
So that the end of riser and the bottom surface of rubber body keep anti-interference distance；Ring spring vibration absorber passes through annular upper bracket
Top surface is connected with the end face of breach and is installed on the breach of rubber bodies.The shortcomings that technical scheme is:Its vibration damping and buffering are led
Vertical direction is acted on, when being installed on the higher equipment back of center of gravity, horizontal direction can not form zero stiffness, subtract with bottom
Vibrating system can not decouple, while the uncontrollable damping in rotary motion.
In addition, the B Chinese patent literatures of CN 104791405 disclose a kind of tooth form vibration isolator, the shock absorber includes two
End is fixed on connecting shaft on support, the middle part set metal circle of the connecting shaft, the quoit it is cylindrical by between axial direction
Elastomeric material external toothing is wrapped every the projection of distribution, the internal tooth of the external tooth and elastomeric material ring gear of the external toothing is nibbled
Close, the ring gear inlays the metal outer shroud inframe for being fixed on axially spaced-apart distributed depressions, the metal outer shroud frame
Side is radially outward from connecting seat.Although the technical scheme, which has, by flank back lash buffer shock-absorbing but also be able to can not only borrow
The advantages of helping the elastic absorbing of the gear teeth itself, vibration isolation, effectiveness in vibration suppression are unique, it is possible to achieve easily regulate and control on demand each firm to vibration damping
Degree and damping characteristic；But practice have shown that the concentric position degree due to interior external tooth can not be ensured, therefore when installation position is equipped with deviation
Without governing loop, the shortcomings that easy clamping stagnation be present；And it can not equally realize the regulation damped under zero stiffness.
The content of the invention
It is an object of the invention to：The shortcomings that existing for above-mentioned prior art limitation, propose that one kind being capable of the side of passing through
Just elastic damping part is chosen to install, so as to easily change --- the damping characteristic including realizing zero stiffness, and can
The microspheric form tooth shape shock absorber of automatic compensation concentricity.
In order to reach object above, microspheric form tooth shape shock absorber basic structure of the invention is：Including being respectively arranged in
The external tooth coil assembly at bow-shaped support both ends, the internal tooth coil assembly for being respectively arranged in vertical central shaft both ends and it is installed on central shaft
The connection cartridge module at middle part；The external tooth coil assembly includes the outer ring being connected with bow-shaped support and the internal tooth being fixed in outer ring
Wheel, the internal tooth coil assembly include the inner ring being connected with central shaft and the external gear that is fixed on outside inner ring, the internal gear and
External gear be intermeshed and at least one be made up of elastomeric material；The connection cartridge module contains forms prismatic pair with central shaft
Sliding block, the sliding block, which has, to be accommodated the inner shaft end cavity volume of connecting shaft and is hinged by ball pivot head and horizontal-extending connecting shaft,
The centre bore of the connecting shaft and ball pivot head, which is formed, moves horizontally pair, the inner parcel elastic buffering pad of the connecting shaft.
Above basic technical scheme causes the microspheric form tooth shape shock absorber of the present invention not only to obtain required polycyclic reduce
Rigidity of shaking and damping characteristic, and multiple combinations relation can be formed, by increasing and decreasing corresponding spring so as to can both pass through structure
The Relative sliding of part obtains zero stiffness, also can by sideshake buffer shock-absorbing and with elastic absorbing, while pre-add can also be passed through
The pressure regulating level frictional force of friction plate, there is unique vibration isolation, vibration damping, buffering effect, specifically can be easily real
The now following respectively regulation and control to vibration damping rigidity and damping characteristic：
1）Support spring is respectively provided between bow-shaped support and the sliding block upper and lower ends, you can required vertical stiffness is produced,
And do not constrained between bow-shaped support and sliding block upper and lower ends, you can realize vertical zero stiffness；
2）The central shaft upper/lower terminal is respectively provided with the outer end cap of the corresponding external tooth coil assembly of pressure holding, so that central shaft loses
Vertical freedom degree, it can only rotate and have that required rotational stiffness --- this rigidity is nibbled by changing the flank of inside and outside gear
It is controllable to close gap；And when central shaft needs horizontal decoupling --- discharge central shaft and make it have flank back lash scope
The horizontal translation free degree when, lay down the constraint of outer end cap, it is very convenient；
3）The central shaft upper/lower terminal is equipped with the outer end cap of the corresponding external tooth coil assembly of pressure holding by friction shim respectively, so
The damping of horizontal Low rigidity can be obtained, the size of damping force is by adjusting press force；
4）Horizontal spring is housed between the inner of the connecting shaft and the end face of shaft end cavity volume, can so obtain required connection
Axle horizontal vibration rigidity；And when not filling this spring, connecting shaft slides in ball socket bearing forms horizontal zero stiffness, and cushion pad
Certain cushioning effect can be played.
As can be seen here, the present invention is by conveniently choosing to install elastic damping part, you can easily changing includes realizing that zero stiffness exists
Interior damping characteristic；And position error can be compensated in certain limit by connecting the spherical hinge structure in cartridge module, avoid clamping stagnation,
Ensure the performance of shock absorber.In addition, the combination of the engagement gear ring and connection component at central shaft both ends of the present invention greatly reduces
Shock absorber volume, it is set easily to install applied to various occasions.
